Roof apertures made in preparation for retrofitting of custom body parts/conversions and high top roofs are currently not available from the factory.

 
Important note:

It is not permitted for the outer roof frame to be machined on vehicles with side head airbags!

The Volkswagen high top roof is offered from the factory for vehicles with wheelbase 3,400 mm only. If custom body manufacturers/coachwork specialists wish to retrofit a high top roof on a vehicle with 3,000 mm or 3,400 mm wheelbase, the following conditions must be met:

1. Vehicles with high sliding doors and/or rear wing doors should not be retrofitted.
2. The roof apertures for both wheelbases should not exceed those shown in the diagrams (see below).
3. The separated bracing elements must be replaced and adapted to the new roof shape.
4. Design of high top roofThe high roof shell should be made of at least 4 mm thick glass-fibre reinforced polyester and should feature a securing flange laminated around its circumference (see below), which should be bonded and screwed to the roof frame.
5. Assembly of high top roof
   The high top roof should be secured sufficiently and sealed around its circumference with AMV 190250.

Roof apertures made in preparation for retrofitting of custom body parts/conversions and high top roofs are currently not available ex-factory.

Retrofitting of roof apertures
Roof apertures can be made between the roof bracing and the side roof frames.
For details, see below.
Warning: The sealing process requires considerable effort due to the
longitudinal swage lines in the roof.
